ADVERTISING DEVICE.

SPECIFICATION forming part of Letters Patent No. 574,277, dated December29, 1896.

Application filed May 23, 1896- Serial No. 592,751. (No model.) Patentedin England November 21, 1895, No. 22,198.

To all LU/1,0777, it may concern:

Be it known that I, FRANK SEPTIMUS DEV- ONTEAUX SCOTT, engineer, asubject of the Queen of Great Britain and Ireland, and a resident of 25Upper Bedford Place, Russell Square, London, England, have inventedcertain new and useful Improvements in and Relating to AdvertisingDevices, (for which I applied for Letters Patent in Great Britain onNovember 21, 1895, No. 22,198,) of which the following is aspecification.

This invention relates to displaying movable advertisements on vehicles,such as omnibuses, tram-cars, carts, and the like.

In order that the invention may he better understood, reference is madeto the accompanying sheet of drawings, in which- Figure 1 illustrates anelevation of an omnibus, showing the invention in the proposed position.Fig. 2 is a front view of the mechanism for imparting a continuousmovement to the strip containing the advertisements when the drums orrollers are revolved. Fig. is a plan of same. Fig. 4 is also a plan, butwith the upper plate removed. Fig. 5 is a side View. Fig. 6 shows thegear for driving the mechanism above referred to. Fig. 7 is a sectionaldetail view.

Similar letters of reference indicate like parts where they occurthroughout the views.

In carrying out the invention I arrange either inside or outside thevehicle and in the most convenient position two drums or rollers A andA, mounted upon spindles B and B and supported by the upper and lowerplates O and O of a suitably-shaped frame D. To each drum is attachedone end of a strip, E, of calico, transparent parchment, or othersuitable material, containing a number of advertisements. Said strip mayhave elastic or other spring ends and may be of any suit-able length,according to the number of advertisements it is desired to display. Eachend portion of said strip is wound upon its respective roller, while theportion between the rollers is earried either around the vehicle insideor outside or along each or both sides, or it can be arranged in anyother suitable position. In order to impart a continuous or, if desired,intermittent rotation to these drums or rollers, so that the endportlons of the strip E will wind first upon one roller and then, whenthis roller is, say, full, wind upon the other roller, I secure to theroller-spindles B and B the toothed wheels F and F, both of which gearwith a similar wheel G, loosely mounted upon the spindle G, on which isalso fixed a cam H, having a peeuliarly-shaped circumferential groove H.

Two clutch-sleeves I and I, each having a tooth or projection J, arearranged upon the spindles B and B and are caused to slide either up ordown, to engage or he disengaged from the clutch-racks K and K, formedon the upper ends of said rollers A and A, by means of the levers L andL, one end of which is pivoted to the brackets L and L and on the otherend are formed the pins L and L to engage the groove II in the cam II.The 10- vers L and L embrace and connect with loose collars situated onthe sleeves I and I, so that said sleeves can rotate with theirrespective spindles, and the springs L may be used to facilitate thedisengaging of the clutches.

To regulate the speed of the cam H, so that one drum shall not be putinto gear until the strip is entirely run off same and the other or fulldrum simultaneouslythrown out of gear, I arrange beneath the upper plateO a ratchetwheel M, having a suitable number of teeth and provided witha spring-pawl M to prevent any backward movement. This wheel M isrotated by an arm M secured to the roller-spindle B, so that at eachrevolution of said spindle B this arm strikes a tooth of theratchet-wheel and slightly turns it. To the spindle of thisratchet-wheel is also secured an arm N, which in like manner rotatesanother ratchet-wheel N, attached to the camspindle G. It will beunderstood that according to the length of the strip E and the speed atwhich the advertisements are required to move so it would be necessaryto increase the number of ratchet-wheels proportionately. hen the stripE has run off either roller, it momentarily stops until the next toothof the ratchet-wheel N is moved by the striking-arm N. To effect therotation of said drums or rollers, I attach to the hub or otherconvenient part of one, or, if necessary, more than one, of thevehicle-wheels (preferably the rear ones) a toothed ring or wheel 0, toengage with a corresponding wheel 0, connected with the lower end of avertical rod 1, which is suitably supported by the brackets P andbearings I" and extends to the upper part of the vehicle and carries onits end a toothed wheel Q, which imparts a rotary movement to the wheelG on the eamspindle aforesaid through the medium ot the wheel Q.

To the vertical rod P is secured a ratchetwheel R, the spring-pawl forwhich is secured to the wheel Q, which is arranged loosely on said rod,so that the mechanism for rotating the rollers carrying theadvertising-strip IE will only be put into operation when the vehicle isgoing forward.

To allow for any vibratory or other movements of the vehicle when going,so that the driving-wheels O and 0 shall be always in gear, I form uponor attach to the bevel-wheel O asleeve 8 to receive the lower end of thevertical rod P. This rod connects with said sleeve by the pin or othersuitable projection S, which is free to move either up or down in theslot S according to the movement of the vehicle.

\Vhen the vehicle is set in motion, the drums or rollers A and A arecaused to ro tate and the strip, or the portion of it that can be wound,passes "from one drum or roller over the pulleys or reels onto the otherdrum or roller, consequently displaying in succession any suitablenumber of, say, different 3 advertisements. i

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In mechanism for advertising pu rposes, the combination of therollers A and A carrying a strip of calico or other suitable materialcontaining ad vertisenients,with a frame D carrying the spindles 3, '3and oi the spindles l3 and 13 having upon them the rollers A and A whichcarry the strip I while on G is the cam II: having a groove II. in whichtwo levers L and Ii engage so as to cause the clutch-sleeves I and I toengage or be disengaged from the cl utch-racks K and K substantially asdescribed.

2. In mechanism for advertising purljioscs, the combination of therollers A and A carrying a strip of calico or other suitable Jmaterialcontaining advertisements, with the wheels F F I and Q with or without(3 for imparting movement to the spindles l3 and II carrying the rollersA and A, the wheels sim i-- lar to M N and striking-arms M: N toregulate the movements ol the cam ll so that its speed shall be inproportion to the length ol
